UNITED STATES PATEN FICE- EMMET'PVQPCSTON, OF SPRINGFIELD, ILLINOIS.

Application filed June 21,

My invention relates to a class pt Inachines adapted to be used forveneerlng and texturing brick units and brick columns from which thebrick units maybe made, preferably while the body of brick is et inplastic torm',' an object being, 111 my cevice particularly to provide asuccesstul means oi projecting granular veneer materials lt'o'rce-*i'iilly into the plastic exposed taces ot the 'bElCh column or brickunit so as to substan-.

iin' object of my invention is to provide a machine by which I maybeable to achieve the 'process 0t veneering and texturlng brick and impactthe veneer materials for which I have'iiled an application for patentbearing Serial Number 200,347 and filed June 21 1927. v

A particular object of myinvention is to providea machine which willtake advantags of the force of gravityto successrully project granularVGHGQE 'DIZLtQYHIlEi into the plastic exposed faces ot brick bodieseither 'incolumn form or in brick units while in plas iccondition andfurther to provide in connection with a machine for pro ecting ven ermaterials for veneering and te ztun Eng brick ameans of mechanicallyaugmentingthe gravitymovement of the veneer materials by rotatablyblasting thesame justbefore they are projected into the plastic brickfaces. I p

i-Liurther object of myinvention is to provide in connec-tion'with amechanical veneering machine a means of moistening the t n'ranu a rveneer n'i'at'eri als.

I ain the objects of my invention in the device describedin thefollowing SPGClilCations, recited in the claims and illustrated in theaccompanying drawings, in whichlilto reference numerals indicate likeparts in the several figures. I -Rcter"ing to the drawings j Figure 1 isa front elevation of the machine 01 my invention.

i-ewith on some occasions suili-L stantially' into thenormally exposedfaces of the clay column or brick unit and left to present a beautiful,rough natural' texture." It Willbe seen that in order to control theflow of veneer particles I providea hand controlled shaft ,7 operativclyregulatinga plurality of gates, 8 which are adapted to controltherelease of'veneerpartic'les from the hopper 1. l

A scraper or cleaner-9 is controlled b hand controlled shaft 10 and isadapted to steam pipe or form contact with a rotating drum within thebase of hopper 1 for moving the veneer particles to the point of releasefrom the hopper.

The drum 23 within the hopperl is rotated by a source of power connectedwith the belt 11. j

Conveyor 12 supports and carries the plastic clay column 14 from the die13.

During the process of veneering the workmen commonly experiencediscomfiturcs and inconveniences about the point of operation unlessthere is a hood 15 provided for confining the dust and steam.

Referring to Fig. 5, it will be noted that water pipe 16 attaches to jet17 at a point that will moisten the projected veneer particles as theyleave the jet, while in. Fig. .6, steam pipe 18 is shown operativelyattached to jet 19 for the same purpose.

It will be seen that jet 19 has provided therein a propeller member 20adapted to be rotated with shaft 21 by a source of powerconnected withbelt pulley 22 for the purpose of boosting and forcefully projecting bya mechanical blast, the moving veneer particles as they leave the tubes.

It will be noted that in the drawings a method of artificially coloringthe plastic column or unit brick is not shown, but is to be regarded asoptional in connection with my machine, and could be accomplished in V avariety of ways, such as for instance by spraying and the like while thecolumn, after vcneering, is yet plastic before firing.

It will be seen in Fig. 3, and in Fig. 1,

that gates 8 are manually controlled by rotating shaft 7, thus providinga convenient means of regulating the release of granular veneerparticles from the hopper l. The position of gates 8 is shown in detailin Fig. 4.

Shafts 10 and 10 are adapted to carry the manually controlled mechanismfor regulating the scraper or cleaner for keeping the grooves inrotating drum 23 clogging under normal operation in order to avoidcongestion.

To the skilled brick manufacturer, it will be evident that the forcewith which the veneer particles may be driven at right angles into theexposed faces of the plastic brick by my machine, will in the gravityfall, depend on the height from which these particles fall, whilefurther variation may be provided in the speed with which propeller 20in jet 19 may be rotated when it is desired to use the same.

Having thus described the machine of my invention, what I claim is:

1. A machine for texturing brick comfrom prising a die for the formationof a plastic brick body, a conveyor for the support and movement of theplastic body, a hopper for the supply of granulartexturing materials, aplurality of relatively high gravity conducting tubes adapted to conductby gravity, said texturingmaterials from said hopper at right angles tosaid plastic body; said tubes terminating at the lower ends in a jetregistering with the exposed faces of the brick body; said jets eachprovided with afluid nozzle for moistening said materials, whereby whencontrollably released from the hopper, said granular texturing materialswill fall from relativelygreat heights, become moistened, and by theforce of the fall, become substantially embedded into the exposedplastic brick faces for forming a veneer therefor. w

2. In a veneering machine of the character described, having a die and aconveyor for the formation and movement of a plastic brick body, ahopper and a plurality oi. gravity conducting tubes; said hoppernormally positioned at a relatively great height above the plastic brickbody for the support of granular veneering materials, and said tubesadapted to accommodate by force of gravity, the passage of said veneermaterials from the hopper at right angles to the exposed faces of theplastic brick body, said tubes provided at their lower terminals withjets adapted to controllably release said ravity accelerated veneermaterials there y projected by the force of their descent andsubstantially embedded into the plastic faces of the brick body.

In a machine of the character described, having a die for the formationof a plastic brick body, a conveyor for the controllable movementthereof, an elevated hopper for containing granular veneering materials,and aplurality of upright tubes adapted to conduct the veneer materialsfrom the hopper at right angles to the brick body, a jet detachablyconnected to the lowor terminals of the tubes and registering with theexposed faces of the brick'body; said jet provided with an enclosedrotatable propeller adapted to be operatively connected with drivingmeans for the mechanical acceleration of the gravity movement of saidveneer materials through the tubes; whereby said materials may beconducted to and substantially projected and embedded into the plasticfaces of the plastic brick body.

In witness whereof, I have hereunto set my signature this 20th day ofJune, A. 1).,
